HOYLAKE, England -- Four players have a chance to unseat Adam Scott and become the No. 1 player in the world should any one of them win the 143rd Open Championship on Sunday.

Henrik Stenson would move up from No. 2 should he win and Scott finish outside the top three. If Justin Rose wins, he takes over No. 1 should Scott finish outside the top six while Bubba Watson gets the top spot if he captures his second major of the season and Scott finishes outside the top 15.

In addition, Jason Day, currently ranked sixth, would go to No. 1 with a win, as long as Scott finishes outside the top 21 and Stenson isn't solo second.

Stenson could also finish second alone and still overtake Scott if neither Rose nor Watson wins and the Aussie finishes outside the top 17. He could also tie for second with one player and still get to No. 1 if Scott misses the cut and Day doesn't win.
